YEAH! I should have thought of this a LONG time ago, enjoy!
Mabel had just started her shift along with Wendy in the Mystery Shack. She sighed.
"Wendy? Will you go wake Dipper up? We need someone to help us."
"Sure, Mabes," She went up the creaky stairs. She opened the door a little, then remembered she should probably knock. She tapped lightly on the border before entering. Upon opening the door she noticed Dipper was talking. "Hey Dipper," She scanned the room and realized he was still in bed, he was sleep talking. She made her way over to his side of the room, paying no mind to what he was saying until one sentence caught her off guard;
"I love you, Wendy..." Her eyes grew wide as he smiled.
"You WHAT?!" She covered her mouth, but too late because he woke up with a start. He let out a girlish scream, Wendy was the next to scream.
"W-What happened?!" He shrieked.
"N-Nothing! We need your help, that's all!" Wendy covered up.
"Then, why did you scream?" He asked, very nervous because he knows he talks in his sleep and he was dreaming about her, he put two and two together.
Her heart was pounding a mile a minute. "I...I saw a mouse! Yeah, it was big and hairy! G-Gotta go!" She raced down the stairs and out the door. She passed Stan and screamed an excuse for leaving early, very quickly.
"HeyStanIHaveSomethingINeedToTakeCareOfSeeYouLater!" Stan just stood there confused.
Wendy ran to her cabin and shut the door as she screamed. Oh my gosh...Dipper...Likes me? She thought as she leaned against the wall. Oh my gosh...I...Like him too?
